Application filed October 26, 1914, Serial No. 868,711.

To all whom it may concern Be it known that I, SALVATORE GUADAG NINO, a subject of the King of Italy, and a resident of the city of New Yorlgborough of Brooklyn, in the county of Kings and State of New York, have invented a newand Improved Vending-Machine, of which the following is a full, clear,- and exact description.

This invention relates to improvements in vending machines, and has for an object to provide an improved construction of a minimum number of parts which are, simple In theaccompanying drawings Figure 1.

is a longitudinal vertical section through a vending 'machine embodying the invention, part of the same being broken away; Fig. 2 is a top plan View of the vending and coin controlled structure; Fig. 3 is a section through Fig. 2 on line 33; Fig. 4 is aview similar to Fig. 2, certain parts having" been removed; Fig. 5 is a section through Fig. 4

on line 5-5;

Referring to the accompanying drawings" by numerals, 1 indicates a suitablecasing of any deslred kind provided with a chute 2 for carrying candy, gum, or other. ar-

y ticles 3. .These articles are designed. to en gage the inner end of the push-rod 4and be moved from the chute 2 as shown in dotted lines in Fig. 1. When a coin of the proper size is inserted into the machine plunger 4 may be moved to the rear once, and then pulled back automatically; A sec ond movement will be prevented unlessanother coin has been inserted. The plunger 4 is provided with a pin 5 and axsp'ring 6 whi'chacts against pin 5 and against a stop 7 so as to normally hold theplunger' in an outer position as shown in Figsxl and 2.

The plunger 4 is mounted in a faceplate '8' and the upstanding stop 7 of plate9. The inner end of plunger 4 is flattened out and receives a plate 10 having a depending'portion 11 projecting through a suitable aperture in the flattened portion 12 of the plunger 4 so that thedepending portion 11 l Y may extendinto an aperture13 of a sliding plate 14.-

The sliding platen Fi 4 b se one jco edge against the guiding barf15 andhas connected therewith near the opposite edge a pivotally mountedmember or plate '16, the

connection being made by a suitable pivotal pin 17.

l The plate 33 is provided with an upi wardly extending tongue 18. Plate 14 is provided with notches 19 and 20 with a rounded projection 22 arranged therebetween. The

extreme front of plate 14 is provided with; 'a beveled edge 23 designedto engage andraise the pin 24 (Fig. 5) when the plate is rn'oving back toiits normal positionas shown in Fig. 4.. The 'pivotallymountedplate 16 is provided with a notch 19 and also a notch 20. together with a projecting portion 22;

. In operation a-coinof the'properis'ize may be fittedv in notches 20 and 20 so as to hold,

' the plate 16in such a position that the spur or pawl shaped member 25 will remain out p of engagement with any of the teeth 26 on the guiding bar 27 as the plunger 4 is moved to the rear. When the plunger has been moved to almost its extreme rear position i the tongue 18 dislo dges the coin frombetween thejaws formed by platesl4 and '16,

7 whereby thecoin may be dropped into} the box 28. V The aperturel? inplate 14is ar ranged abovea slot-29, which slot accommo dates the lower portion of the extension 11 so asto guide the same in the reciprocatory movement of the plungers4. A spring30 is" and thereby lock theplate 14 I against movement.

i It willbe noted that the spring 30 I I substantially U-shaped whereby long fside' edges are presented which will continue to engage the plate 16 even though; the same; 'may be moved to the rear an appreciable 1 arrangedbetween the plate 16 andbar 27 so as to normally press the bar 25 into teeth 26 distance. It will be noted that between the 7 plate 116 and plate 14 is a space 31 which ac 'commodates the stop 32socured to the; base 5 the coin designed to be used is force'dintov plate 33. If, for instance, a coin larger than theflnotch es20 and 2,0 the plate 16 will be I moved pivotally until the corner 34of'plate 16 will strike against pin 32 in case the plunger is moved toward the'rear. 'Amove ment of this character will not be suflicient 1 j for dislodging one 'ofthe packages 3from; i

chute 2 so that a larger coin will not operate the device. However, the eXtra large coin will be engaged by the tongue 18 and dislodged. If for any reason the extra large coin should not be discharged the next succeeding coin of the proper size will dislodge the extra large coin and force the same into the receptacle 28.

The plate 9 is provided with an aperture while plate 1%- is provided with an aper ture 36, these apertures being designed to receive the pins 2% and 87, respectively. The pins. as and 37 are beveled in opposite directions so .that the pin 37 has the bevel facing the front plate 8 as shown in Fig. 1, while pin in has the bevel facing in the opposite direction so as to. engage the beveled edge 23. Pin 37 is arranged centrally of the space between sockets 20 and 2 so as to fit into the aperture of a washer and thereby prevent, any engagement of the plunger. Also by reason of the aperture, in the washer the pin 24.- will not be raised but will remain in the aperture 35. t I

Pins 24: and 37 are rigidly secured to a spring plate 38 which is preferably pro vided with a bowed portion 39 so as to give a better resilient efiect. Also a spring so, is provided held in place by a suitable screw ll for resiliently holding the end of plate 38 against plate 9. As shown in Figs. 1 and 3 the spring plate 38 is held at one end by a screw 42 firmly to plate 9. acts as means for clamping plate 9, bar 27 and base 33 together though suitable rivets are preferably provided for rigidly securing bars 15 and 27 rigidly to base 33.

In operation after the parts have been as-. sembled as shown in Fig. l a coin is inserted as for instance a one cent piece, the same being forced through the slot 43. When the coin is forced through the slot 43 the same engages the forward ends of plates 14 and 1G and moves pivotal plate 16 from plate 14; so. that the coin may pass into the notches 20 and 20. The plunger 4t is then forced inwardly until the lowermost packet 3 has been forced off the chute 2, as shown in dotted lines in Fig. l. The one cent pieceis,

of such a size as to hold the pawl 25 out of engagement wlth teeth 26, and also to, hold the point 3% a suflicient distance from stop.

82 for preventing a free passage. Upon the completion or near completion of the inward movement of plunger 4; tongue 18 will engage the one cent piece and force the same out of contact with plates i l and 16, so that the coin will drop into the receptacle 28. If a washer of the same size and thickness as the one cent piece is forced into the sockets 20 and 20. no result will follow. The plunger cannot be forced inwardly after this has been done, but a one cent piece may be easily forced into position in the sockets 20 and 2Q, forcing the washer out of said sock- Screw 42 also ets and causing the same to fall into the receptacle 28. hen this has been done the plunger may be moved to the rear as above forth. By this construction and arrangement it will be observed that the device'will not become out of order when a washer been inserted but will merely refuse to operate until a coin of the correct size has been placed in position. When a coin, as for instance, a one cent piece is forced into sock-- ets 20 and 20" the same raises pin 3.? and holds the same raised. The raising of pin f co-ursecraises the plate 38 and pin 2%, whereby the sliding plate l t-is free to move. When a washer is in soclzetsQO and ZOpin 37 is ofcourse projecting into. the hole in the washer. so that pin 2% is still in engagement with the plate 9 as the same is still projecting into aperture 3 5. It will be evi dent that suitable apertures are provided in plate 9 for accommodating pins 2 and 37 shown in Fig. 5. If a coin is inserted into the notches 20, 20. which is smaller than is intended to be received by the device said coin willnot injure the device any way nor, will it work the same, but will be lost to they would be purchaser. Eor instance, if the device was arranged to utilise a one cent piece and then a ten cent piece was inserted the ten cent piece would be forced into the receptacle 28 ina similar mannerto the way a washer is forced into said receptacle.

Plate 14 is provided with a pin set which extends into a slot 45 formed in the base 33. This is to, limit the reciprocatory movement of the plate. As shown inEig. 41, the end of the pivotally mounted member 16v which engages the coin as the coin passes through the front plate 8 is provided with a pointed end 1-6 which wilt prevent the use of lead slugs, paper or pieces of weed, as such matter will be entered by point 4-6 and will therefore not operate the machine.
